安装

SET UP THE REPOSITORY

相关包

yum-utils provides the yum-config-manager utility, and device-mapper-persistent-data and lvm2 are required by the devicemapper storage driver

sudo yum install -y yum-utils \
  device-mapper-persistent-data \
  lvm2

set up the stable repository

sudo yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo
    
sudo yum makecache fast

sudo yum-config-manager --disable docker-ce-edge

官方文档，路径错误

INSTALL DOCKER CE

sudo yum install docker-ce

On production systems, you should install a specific version of Docker CE instead of always using the latest.

yum list docker-ce --showduplicates | sort -r

sudo yum install <FULLY-QUALIFIED-PACKAGE-NAME>

Start Docker

sudo systemctl start docker
sudo systemctl enable docker

Verify

sudo docker run hello-world

基本命令

sudo docker search centos # ubuntu, fedora
sudo docker pull centos
sudo docker pull httpd
# check if docker images downloaded
sudo docker images centos

# run docker
sudo docker run -i -t centos /bin/bash
sudo docker run -d -p 80:80 httpd

# current running list
sudo docker ps

命令过程

docker run -d -p 80:80 httpd

其过程可以简单的描述为：

从 Docker Hub 下载 httpd 镜像。镜像中已经安装好了 Apache HTTP Server。
启动 httpd 容器，并将容器的 80 端口映射到 host 的 80 端口。
下面我们可以通过浏览器验证容器是否正常工作。在浏览器中输入 http://[your ubuntu host IP]

Uninstall Docker CE

Uninstall the Docker package

sudo yum remove docker-ce

Images, containers, volumes, or customized configuration files on your host are not automatically removed. To delete all images, containers, and volumes:

sudo rm -rf /var/lib/docker
